Fixing the Fix - How Much Does it Really Cost?

[article]
Summary:

I think everyone in our industry has heard at one time or another "It costs 3x more to fix software after deployment to production than it does fixing it right the first time." My question is; How do we prove that statement?

We all know that there are costs of people-hours associated with "Fixing the Fix" but how do we quantify some of the other factors, such as; downtime, Feature - non-Fuctional time, user and customer inconvenience, Frustration, Loss of credibility, etc... Is there a good formula out there that actually works?
